instal gtk on windows

["nostradamo" <nostradamo de web de>]

I installed gtk2 on windows. I want 
compile with gcc. but compiler can not find the hedaer files. 

For example gtk.h

Ich i make a include with
"dir direkt to gtk.h" a list of a lot of unknow files und dirs will be showed.

What is wront. or what does i have to do that compiler can work correct

compiler is working with

g++ file.c
